520 ▼a The focus of this work is to investigate the timing of early Laramide magmatic events at several localities in southern Arizona (Silver Bell, Chilito/Christmas, Copper Creek, San Manuel, Cerro Colorado/Oro Blanco districts, Rosemont, Ajo, Texas
520 ▼a The objectives of this investigation are accomplished through systematic collection of early Laramide volcanic and intrusive rocks in mineral districts and areas adjacent to or believed to be associated with or known to host porphyry copper. Thi
520 ▼a The results of this investigation show that there is no single early Laramide volcanic unit that predates porphyry copper mineralization regionally. Geographic exposures of early Laramide volcanic rocks are distinct in age and may predate nearby
